Driving at night stands for navigating through uncertainty, seeing only as far as your own lights reach. Tradition reads it as quiet reflection, or as feeling your way through an unclear phase.
Has this come up in your dreams before? What was going on in your life then?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
